A mouse model of Greig cephalapolysyndactyly syndrome: the extra-toesJ mutationcontains an intragenic deletion of the Gli3 geneChi-chung Hui & Alexandra L. Joyner

Nature Genet. 3, 241–246 (1993).

Originally, we reported that the 3´ end of Gli3 is not deleted in the XtJ allele (Fig. 4). U. Rüther brought to our attention that the XtJ alleleindeed contains a deletion including the 3´ UTR of Gli3. Subsequently, we repeated the experiments and found that the data described inFig. 4 using probe d was due to probe d containing sequences other than Gli3. These findings indicate that the deletion in the XtJ allelemight not be intragenic; however, it does not affect our main conclusion that XtJ is a mouse model of GCPS. We regret this error.

Spelling errors were inadvertantly made in the names of two co-authors: Sergiu Blumen and Amos D. Korczyn. We apologize forthese mistakes.

Bleomycin hydrolase is associated with risk of sporadic Alzheimer’s diseaseSusana E. Montoya et al.

Due to a typographical error, the genotypefrequencies for the ADRC confirmed casesin Table 1 were reported incorrectly as0.426 instead of 0.490. The corrected tableis shown on the right. We regret this error.
